I am in the middle of figuring out plumbing returns and over flows and I can't figure out how to set up my returns for a sleek look. I'm building a custom 450 gal. I am running a hammerhead/ barracuda reeflo from my basement. I know the outlet is inch and a half. I was debating on using loc line to return and just splitting it or having multiple larger loc line returns. I am worried about reducing my return lines and loosing head pressure. I have ruffly 17 ft of head pressure
